I worked with a complete asshole who would go out of his way to be a huge dick to me. If there was a weakness, he'd exploit it.

One day, he privately pulled me aside and touched my neck and cheek area, said, "You should shave here and here. Tighten it up. Makes you look more presentable."

No joke. No mockery. Just a heads up from the biggest asshole I ever met. And he was right. That was twenty years ago, and I think about that every time I shave there.
